Employee Benefit Plans
 
401(k) Plan
 
The Company has a 401(k) plan, which covers substantially all employees. Participants in the plan may contribute a percentage of compensation, but not in excess of the maximum allowed under the Internal Revenue Code. In 2011 and 2010, the plan did not provide for matching contributions.
